But this latest one – FIT SMART -- will stand out from the rest, an Adidas executive claimed Wednesday, because of its multiple features.

"It's a personal fitness coach for your wrist," Paul Gaudio, general manager of digital sports at Adidas, said in the interview. "That's the fundamental difference."

The biggest difference between FIT SMART and competitors' wristband fitness devices, Gaudio said, is that Adidas' has a built-in heart rate monitor.

"It's one thing to know how you're exercising," he said, "it's another thing to know how your heart responds to that exercising."

Gaudio introduced the device Wednesday in a keynote address delivered at the Wearable Technologies Conference 2014 in San Francisco. While many of Adidas' digital products are developed at its North American headquarters in Portland, the FIT SMART was developed at Adidas' corporate home in Herzogenaurach, Germany.

Gaudio, in the interview, noted that six years have elapsed since Adidas introduced its first personal digital-recording device through it miCoach system of products.

FIT SMART stores up to 10 hours of workout data and syncs with the miCoach platform using Bluetooth on the user's mobile phone. The app offers training advice as well as helping set training goals based on performance.

The FIT SMART will retail for $199. By contrast, on Amazon, the Nike+ Fuel Band ranges from $83 to $299.99; Fitbit Flex Wireless Activity Wristband is $99.95; and the UP Jawbone ranged from $77.50 to $137.22.

Consumers will recognize, Gaudio said, that FIT SMART's functions offer more for their money.

"They'll look at the experience that we deliver," he said. "The capabilities are at a different level. If you purchase the product you'll get taken on a much deeper and relevant journey."

The product as well as the app will be released in late August. In the U.S., FIT SMART will initially be offered only at leading Best Buy and bestbuy.com, with availability later at adidas.com, Adidas Sport Performance stores and other retailers.
